Briquette coal storage bin with anti-blocking charging barrel

The invention relates to the technical field of chemical fertilizer preparation equipment, in particular to an anti-blocking charging barrel type coal storage bunker which comprises a barrel body, a stacking density control device is arranged in the barrel body and comprises an isolation device arranged at the 1/3-2/5 position of the height of the barrel body, the isolation device divides the barrel body into a storage bin and a discharging bin, and the storage bin and the discharging bin are arranged in the barrel body. The discharging speed and the material amount of the discharging bin are controlled through the opening adjusting device, then the stacking density of the discharging bin can be effectively controlled, under the condition of the same discharging speed, the discharging weight is stable, the discharging bin pressure is controlled through the discharging bin pressure control device, then the discharging bin pressure and the stacking density are stable, and the pressure sensor is arranged, so tha
